How Do I Choose the Right Size Medela Breastshield?

Selecting the correct size breastshield for your Medela breast pump is crucial for successful pumping. The breastshield is the part of the pump that fits over your nipple and forms a seal around your areola. It is available in five sizes; a medium shield comes with the pump. A shield that is too small will rub against your nipple, causing irritation or even injury and constricting your milk ducts, which inhibits milk flow. But if your shield is too large, you will be unable to get effective suction.

Instructions

1

Insert your nipple into the breastshield, making sure the wide part of the funnel is against your breast and the small end is securely attached to the pump itself.

2

Turn on the power switch on the back of the yellow power supply on your pump. You should immediately feel a vacuum sensation. Adjust the suction power with the same switch that turns the pump on.

3

Watch your nipple as it is pulled to see if it moves freely. Your nipple should not rub against the sides of the shield. If the shield is too small, the constant friction of your nipple against the sides will cause tenderness or even scraping of your nipple, leaving visible flecks in the shield.

4

Watch to see if your nipple is moving with the suction of the pump. The suction should pull your nipple comfortably into the tunnel, and the movement should be visible through the shield.

5

Make sure that the pump is not too large to form an effective seal against your breast. A lack of seal will cause lose of suction--and little or no breast milk be pumped from your breast.
